HOT PEREZ. HP-1 circuit clone. The HP-1of course does not seem to have one stock design in terms of part values as slight changes were made over its small lifecycle. Much internet sleuthing on behalf of many people has come up with what are the various HP-1 variables, and this one is the schematic version purported to be closest to steve's HP-1. Its a little more smooth and less wild than some of the other variants. These are using germanium diodes spec matched to the OG 1N695 diodes in the original, an AC125 germanium transistor, and a 2N3565 silicon transistor.
